On March 2010 the Star Trek Elite Force II Master Server disappeared the first time, it was then when GSIO, a Member of the Elite Force II community created a new Master Server. This new Community Master Server is now hosted by the SFU Clan.

That is the reason why you can't find any EF2 Internet Servers even thou there are currently 3 public servers online 24/7

You will need to make adjustments for the game to accept the alternative Master-Server!This Article explains you how to make these alterations. These changes will make your computer use a different IP for the address of the Activision ef2 master-server, this is necessary since the game offers no option to change the master server from within the game it self.

The easiest method for all Windows Users would be to run the EF2 Master-Server Toogle fix patch.
